Crash and occupant safety analysis software
must be able to handle large deformations, sophisticated
material models (for steel and aluminum, rubbers, foams,
plastics, and composites), complex contact conditions among
multiple components, and short-duration impact dynamics. The
software must be capable of simulating different types of car
crash events: frontal impact, side impact, rear impact, and
rollover.

Crashworthiness simulation is less expensive
and yields more information than experimental techniques.
Because of its extensive capabilities for handling
crashworthiness and occupant safety simulations, LS-DYNA is used
worldwide by leading automobile manufacturers and their
suppliers.
